This 'iconic' look at 'The Return of Doctor Mysterio' keeps the Time Lord (Peter Capaldi) on his toes as he dodges a literal superhero known as The Ghost - played by the dashing Justin Chatwin.

This year's Christmas special sets the TARDIS down in New York City, as The Doctor joins forces with an investigative reporter (Charity Wakefield) and his old friend Nardole (Matt Lucas) to track down this mysterious superhero.

Capaldi and showrunner Steven Moffat are already setting our expectations high for 'The Return of Doctor Mysterio' by comparing it to classic superhero movies like 1978's Superman.

"I was obsessed with superheroes when I was a kid," Moffat told fans at New York Comic-Con this autumn. "Mainly, what I liked was Superman. And mainly what I liked about Superman was Clark Kent.

"Clark Kent is awesome. He's amazing. He goes around pretending he's not a god and not revealing to the woman he loves that he is the man she's in love with for her own protection. It's the best love story ever told. I love that. It's a love triangle with two people in it.

"And I've always wanted to write that story. I've always loved Clark Kent. Clark Kent is the best hero ever. Every hero since then has been dispensable... apart from Doctor Who and Sherlock Holmes!"
